apache/pulsar has 15.4k stars and gained +15 of them in the last 30 days, a 0.1% change. It is written in Java, grouped under data, networking, released under Apache-2.0. A merged pull request waits a median of 17h from opening to merge, measured on 370 pull requests. Last pushed on 27 Oct 2026.
Star growth per time window: stars gained, growth percentage, the star count at the start of the period, and whether the figure was measured from our own two-hour intraday snapshots, daily snapshots, or GitHub’s rebuilt star history, for the last 6 hours, the last 12 hours, today, the last 7 days, the last 30 days, and the last year. A period with no current measurement is left blank rather than shown as zero.

A period with no current measurement is left blank: a delta needs a measurement at both ends of the period. The 6- and 12-hour periods need two intraday measurements exactly that far apart, the day-and-longer periods need snapshots on both dates, and the last year also needs star history from a year ago, which we keep for one year.

It definitely is on the more complex side of management. That's why we partnered with Kafkaesque to do the maintenance for us. We were fine handling it ourselves but decided to outsource it as it's less critical for us than many other internal tasks. They have an open ticket [0] to dilute zookeeper's dependance, but as far as I know it's still pending. [0] https://github.com/apache/pulsar/issues/…
Unlike Kafka, and despite some unfortunately misleading wordings in articles and documentation pages, Pulsar doesn't actually support exactly-once aka 'effectively-once' semantics because it lacks support for transactions. It only supports an idempotent producer combined with message deduplication. The current functionality only works when producing one message and to only one partition. For exam…

Stars: 15.3k when it entered our index, 15.4k on the last capture we hold (26 Oct 2026), so +13 in that span. That span is our own measurement window, not a claim about what happened before it.
Its most recent thread before Trending is more than 90 days older than that day, so the two are not the same story and we do not claim lead time.
We hold 8 mentions for it, the oldest dated 11 Jan 2019 and the first written into our database on 27 Oct 2026. Thread dates come from the source, not from when we fetched them.
Where it stands

This repository has not been picked up by the newest daily run yet, so these figures are from 26 Oct 2026 (yesterday). They will refresh on its next run.

Reddit (fetched when this page is opened)
A Reddit search for github.com/apache/pulsar runs while this page is rendered, at most once every 6 hours per repository. What it finds is stored in our database (25 posts per fetch, at most 200 repositories a day), so the numbers on this site can be reproduced later. Reddit's feed has no scores or comment counts, so none are shown.
